Abstract
Based on atmospheric circulation reanalysis, global gridded precipitation, and outgoing longwave radiation datasets, this study reveals the physical process through which the land–sea thermal contrast over East Asia interrelates with the variability of the interface between the Indian summer monsoon and East Asian summer monsoon (IIE). The results indicate that the release of latent heating exerted by the low-frequency variability of anomalous land–sea thermal contrast is one of the most important physical processes correlating with the zonal movement of the IIE, in which the release of latent heating over eastern East Asia makes the greatest contribution. When a lower apparent moisture sink occurs over the South China Sea but a higher one over southern China, an anomalously positive land–sea thermal contrast is formed. An anomalous convergent zone in relation to the positive land–sea thermal contrast, located in the eastern part of the IIE, will favor the IIE to move more eastward than normal, and vice versa. An anomalous divergent zone located in the eastern part of the IIE will benefit the IIE to shift more westward than normal. Experiments using a linear baroclinic model confirm the physical processes revealed by the observational analysis.
